Abstract. An introductory chemistry laboratory designed for an advanced high school or a college environment is presented. The experiment uses the enzyme catalase to catalyze the breakdown of hydrogen peroxide. The experiment covers important concepts including reaction rates, order of reaction, oxidation–reduction, plotting and analyzing data, and enzyme catalysis. This experiment was developed as part of a continuing curriculum reform effort in our introductory chemistry laboratories to integrate biological and chemical concepts, to reduce "cookbook" procedures, and to foster greater student engagement in the learning process.
